The device can have from 4 to 32 GB of storing memory. Adoptation to a larger memory (64, 128, 256 GB, etc.) is possible. Simultaneously the device became approximately two times shorter. This became possible due to exploiting of the microSDHC card instead of the standard SD card used before.

The modification of the logger used on ostrichs was equipped with a three-dimensional accelerometer, sampled with the same rate as EEG channels. This version of the logger also can be used just as a 3-D storing accelerometer, if EEG channels are not needed.

The power consumption of this modification is approximately 40% smaller against the original version.

Neurologger also can be used for storing data from the external equipment sent through the serial port. It recorded circadian activity of mice in the field (Daan et al., 2011) and high-resolution trajectory of wandering albatrosses (Sachs et al., 2012).
